Data Recording

Data recording allows you to capture all (or part) of monitored data to the disk file for subsequent analysis. This section tells you how to create log files. The Playback section tells you how to play back previously recorded log files. The Tools » Settings, Recording/Playback Tab section describes Data Recording and Playback configuration options.

Log File Structure

Every single log file consists of several streams. Each time you start a monitoring session with Data Recording processing module, new log file is created for it. Sessions Tool Window lists all data processing modules for a session, including the Data Recording. The State column shows the total amount of data saved to a log file in bytes. It also allows you to press the End Stream button to stop current stream. The button changes to New Stream after that. Press it again to start new stream within the same log file.

Configuring Data Recording

Data recording is taking place whenever a Data Recording processing module is added to a monitoring session. If you remove this processing module from a running session, recording stops; if you add this module to a running session, recording starts to a new log file. You cannot add more than one Data Recording module to a session.

For convenience, the following commands may be used as alternative:

Tools » Start/Resume Recording

Adds a Data Recording processing module to the current monitoring session or starts new stream if it has already been added.

Tools » Pause Recording

Ends the current stream and pauses recording.

Tools » Stop Recording

Removes a Data Recording processing module from the current monitoring session.

If you want to record new monitoring session from the very start, add the Data Recording processing module when you configure new monitoring session in Session Configuration Window.
